Washington is in the middle of a whooping cough (pertussis) epidemic. Whooping cough spreads easily by coughing and sneezing. It is a very serious illness for babies and children. Vaccination is the best protection against whooping cough.
To learn more about pertussis and what you can do to protect yourself and others, please visit the Washington State Department of Health's page about the 2012 epidemic. Resources for parents are available in multiple languages and pertussis statistics for the state are updated weekly. http://www.doh.wa.gov/Topics/pertussis2012/
